The IFX007T is an integrated high current half bridge for motor drive applications. It is part of the Industrial &Multi PurposeNovalithIC™ family containing one p-channel high-side MOSFET and one n-channel low-sideMOSFET with an integrated driver IC in one package. Due to the p-channel high-side switch the need for acharge pump is eliminated thus minimizing EMI. Interfacing to a microcontroller is made easy by theintegrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, deadtime generation and protection against overtemperature, undervoltage, overcurrent and short circuit.
